To all whom t may concern.'

Be it known that I, FRANCISCO CLARK, a citizen of Mexico, and a resident of Durango cityin the State of Durango and Republic of Mexico, have invented anew and Improved Adjustable Tumbler-Loek, of

. which the following is a full, clear, and

exact description.

Thisinvention relates to a new and improved lock and more particularly to a lock of the combination type.

The inventor is aware that heretofore.

there have been various constructions suggested for a combination lock, but such devices have involved complicated constructions and the use of many partsand have necessitated the use of a key having akcomplicated construction in connection therewith, and further in the use of a combination key with a lock, it has necessitated further movement of the key in order to release the locking mechanism after the key has been positioned in the keyhole. Such locks are easily rendered inoperative if dirt or' other particles become lodged in the keyhole, they beingof such construction as to -make it extremely diflicult, if not impossible,

to remove the same.

One of the objects of this invention is to overcome the objections above noted in combination loc-ks heretofore provided and to provide a lock of simple construction, havfew parts, compactly arranged, and which may be relatively inexpensive to manufac- 35 key therein will bring the mechanism of the lock in ,such a position as will permit the latch or bolt member of the lock to freely move without further movement of the key.

Still another object of this invention is toprovide a lock so constructed as to make it impossible to use a master key thereon or to obtain an impression of any kind that will permit a key to be made to release the lock without having knowledge of the com.-

' bination ofthe lock.

Still another object is to provide a combi nation lock, which is adapted to be used with a combination key which is positively held in position whenthe key is inserted in the keyhole without further movement thereof, and will permit the bolt or latch member of the lock to be freely moved.

The above objects are substantially accomplished by providing in a combination lock a plurality of tumblers which preferably are of uniform construction, having positioned thereon a lurality `of adjustable peg members so positioned that when a combination key is inserted within the keyhole, having ward members set to correspond with the setting` of the pegs in the tumbler members, a pathway will be afforded to permit free movement of the bolt or latch member of the lock. In the preferred construction a spring member is used to actuate the bolt member when the key is inserted, but if desired, a separate means may be provided for obtaining movement of the bolt member when the key is inserted in the keyhole. l

A further object of this invention is to provide a universal combination lock to be used with a combination key, it being universal in the respect that knowing the combination'thereof any combination key to be used therewith may be' changed to correspond therewith, the lock being so oonstructed that the setting thereof may readily be changed to form a different combination nd necessitate a resetting of the key there- Other objects and advantages will be apparent from the following description and the accompanyingdrawings in which similar characters of' reference designate like parts in the several views.

In the drawings showing one of the preferred constructions, the lock comprises a base 1, substantially rectangular in form, which preferably is made of suitable cast metal. The base is provided with an opening 2 through which extends a plurality of tumbler members orbars 3, 4, 5, 6 and 7, which preferably may be of uniform, or if desired, identical construction, it being understood that any desired ynumber of tumblers may herein shown five for y purposes of illustration.

Each of the Itumbler members, in the preferred form, comprises rectangular bars having a tapered -surface 8 at one end thereof, the purpose of which will later be seen. VThe forward end of the tumblers slide within a keyhole housing 9 which is shown as a rectangular-shapedtube formed to embrace the said tumbler members, there being provided at one end of the keyhole housing a flange 10, which is positioned about the edge of the opening. 2 andlis held in position on the baseI lby screws 11 or other suitable means.

lhe'end' ofthe keyhole housing 9 extends beyond the tapered end 8 of the tumbler members and forms a keyhole opening 12 in whichy longitudinally projecting ward memb ers 13, 14, 15, 16 and I17, extending from a key body 18, may extend the said ward members corresponding in number with the tumblers and engaging the corresponding tumbler members when the key is inserted in the keyhole 12.

In the preferred construction, there is provided for each one ofthe tumbler members a plurality of pegs 19, the'bottom portion of said pegs being positionedin openings 20 of suitable shape-spaced-'in the tumbler members, the said openings 20 and' pegs 19'being preferably cylindrical in form. If desired, the openings 20 may have conical shaped bottoms to facilitate the seating of the pegs, and the upper peg portion projecting above the tumbler bar may be, if desired, square in form as shown in Figs. 9 and 10. Preferably the upper portion of the peg yet extending above the bar is of a larger dimension than the portion extending within the hole, this insuring that the portions of the pegs extending above said bar will be of equal length. The pegs 19 are preferably positioned at the end of the tumbler bars.

Alny suitable number of pegs may be used, but preferably the number of openings provided will exceed by three the number of tumbler members or the corresponding mimber of ward members for the key which are used. Further in the preferred form, the number of pegs 19 provided will be two less than the -number of holes provided in the tumbler members. the purpose of which will later be seen.

ln the positioning of the pegs 19, it is desirable that a peg be permanently positioned in each of the end openings in each of the tumbler members, the one nearer the center of each of the tumblers coming in Contact with the flange 10 of the keyhole housing 9 to limit the movement of the bars in one direction. The purpose of having the other end peg permanently maintained in position will later bey explained.

The ward members of the key 18 are positively held in the keyhole 12 by a projecting lip 21 carried by the key body forward of the end thereof, the said lip 21 engaging a slotted opening 22 positioned in one side of the keyhole housing. Each of the tumbler members is normally held in a forward position with the peg 19 in contact with the flange l() by a spring member 23 engaging the respective tumbler members.

Ihe'springmembers in the preferred form are shown as fla-t leaf springs having one end thereof engaging one end of the tumbler members, the other end of said spring 23 being fixed between two plate members 24. 25, which are held together by a screw 26 or other suitable connection. It is thus seen thatthere is provided an independent spring member 23 for each llO y of the tumblers, the said spring members functioning to push tion, the top edge further serves as a guide or rest on which "a bolt or latch member 27 may ride.

In the preferred form, the bolt 27 is thus seen to move laterally or transversely of the ltumbler members, the said bolt 27 being provided with a cut-out portion 28 xforming the web portions 29, 30, the thickness of the web portion adjacent to the tumbler r members being slightly less than that occupied by two adjacent pegs of the tumbler mem- "bers or, in other words, the web 29 being of such a thickness as will permit saidfweb to pass freely transversely of the tumbler mem- 27. By providing a construction vwhereby each ofthe tumbler members have an equal movement when pressed rearwardly against the spring, it practically eliminates the possibility of an unauthorized person obtaining j the combination of the lock and prevents the use of the usual master key.v In otherI words, the effective positioning of the tumbler members to permit a movement of the bolt can in no .way be determined by a moyement of the various tumbler members to an extreme rearward position. l

As a means of holding the bolt'member of the lock normally against movement when the key is not inserted Within the keyhole,`

one the web ,portions 29 adjacent the inner end of thetumbler members is provided y with a series of slots 31, the said slots being of such a depth and thickness as to permit' the peg members 19 to move therethrough,

I the number of slots in one series correspond- `ing in number to the number of ward members having pegs thereur.` It 1s thus seen that the pegs in the w'ard members' extending lWithin the slots 3 1 of the bolt prevent the movement of the bolt member.

. It is now -to be seen the` importance of having at least-one end 'peg in each of the ward members, this being necessary in order -`that at least one peg of ,each of the ward members shall be positioned in each oneJ of the series of slots when the key is not posi@ tioned` in the keyhole. This is in order to prevent the movement ofthe bolt until the key has properly positioned the tumbler members for such .a movement.

Another seriesofslots 32 is provided' in another part ofthe vweb spaced from the first-mentioned series of slots 31 by ra. spacv the tumbler members. p 2 the tumblers 7 6, 5, 4, 3 would have to be also corresponding in number and size to the first series of slots 31, the -respective series of slots 31 and 32 functioning to receive the pegs of the corresponding tumbler members at the limits of movement of the bolt -member 27.

In the preferred construction shown, preferably two adjacent pegs have been removed from each of the tumbler members, thus leaving a space or pathway 34 thereinof suiicient size to permit the web 29 to pass therethrou h when in alinement therewith. The bolt 2 could not move until the space or pathway 34 of each of the tumbler members has been brought into alinement.with the web 29 or, in other words, until the space or path 34 of each of the tumbler members has been brought in alinement with the series of slots .31 or 32 depending upon which series of slots is in alinement with the peg members,

In order that the spaces 34 may be brought into alinement with the key, the various tumbler members must be moved a distance corresponding to the distance that the space 34 is positioned from the end of For example, in Fig.

moved a distance. corresponding to 4, 2, 3, 2, 4 pegsrespectively andheld in such a position, at which time the web 29 ofthe bolt 27 would then be free to move through the'path formed by the alined spaces 34 of 4the various tumbler members, as seen in Fig. 4 showing the ward members 13, 14, 15, 16 and 17, extending within the keyhole and in contact with the tumbler members 7, 6, 5, 4, 3,-respectively.

It is here to be noted that the setting of the various ward members of the key corresponds tothe setting of the pegs in the respective tumblers. 1

It is here to be further noted that if any one of the ward members of the key were improperly :set with reference to the positioning `of the pegs in the tumbler` member corresponding to such .a Ward member, it would be impossible to mo've the bolt 27, thus making it necessary thatthe exact setting or'combination of the lock be known in rorder that the keyl may be set to correspond therewith.

As heretofore stated, the ward members `projectin, from the end of the key body 18 are held within the keyhole 12 in contact with the respective spring actuated tumbler members `and is there positively held,

the end of the tumbler members, thetaper being in such a,direct'ion aswill keep the projecting lip 21 positioned 1n the slot 22.

in the preferred form shown, bythe prof- 4 jecting lip 21 extending Yin the slot 22. The i ends of the ward members have a-tapered surface to correspond with the taper, 8 atl 4 65 At each end of the lock 39 there is provided In the preferred construction shown, the

thickness of the ward members will be slightly less than the size of the keyhole 12, this being necessary in order to permit the positioning of the projecting lip 21, but it is understood that any suitable means of holding the key in its effective position may be provided.

In the preferred construction shown, as one means of limiting the movement of the bolt 27, there is provided a slotted opening in the base 1, which is of a length corresponding to the movement desired of the bolt 27, the said bolt having a stud 36, the stud 36 preferably being of such a length that the end thereof will extend through the slot 35 to the opposite side of the base 1, as shown in Fig. 1.

rlhe bolt member may be automatically actuated by a spring in one direction, if desired, and for this purpose there is provided a. spring 37, which, in the preferred form, is

.set in a sunken portion 38 on one side of the base 1, one end of the spring being held against movement and the other end engaging the stud 36 so that if the bolt 27 extends outward of the lock, as for example when the parts are in a locked position and `the key is inserted within the keyhole to bring the tumbler members so that the open paths .34 of each of the tumbler members will be in alinement with the web 29 of the bolt, the said bolt`will be moved automatically inward of the lock by the spring 37. It is thus seen that it requires only the insertion of the key without further movement thereof in order that the bolt may be withdrawn.

It is understood that any suitable spring arrangement may be employed to effect movement of the bolt as the invention is not to be limited to the arrangement shown.

f As a means of moving the bolt 27 when a .spring is not used, the bolt is provided with a toothed rack surface 39, shown in the drawings as being positioned on the upper edge of the bolt opposite to the positioning of the series of slots 31, 32, there being further provided a pinion 40 meshing with the toothed rack 39, the said pinion being carried on astem 41 extending through the base 1, so that one end thereof 42 extends outward of the main body of the lock so as f to be in substantial alinement with the outer edge of the keyhole housing 9, there being l providedin the end of the said stem an opening 43 in which an instrument or key may be inserted in order that the pinion 40 may be rotated to move the bolt 27 in the desired direction. The key would be positioned within the keyhole in order to permit the free sliding movement of the bolt as actuated by the stem 41 through the pinion and rack connection, 40 and 39 respectively.

a raised shoulder 44, which constructicni` also serves as another means of limiting the movement of the bolt 27.

A suitable casing is provided for the lock which preferably comprises two parts, a front cover or casing 45 and a rear cover or casing 46. The front cover or casing is provided with an opening through which the keyhole housing 9 extends and is provided with another opening to receive the stem 41, there being provided about said opening a protective casing 47, which, in the preferred form. is shown integral with the front easiing 45 and is tubular in form having the end thereof extending outwardly so as to be in Substantial alinement with the keyhole 12. The said protective casing 47 serves to prevent the'stem from being damaged.

The front casing 45 is further provided with extending side portions 48, the said front casing being held ifn position preferably by screws extending through the sides 48 and threaded in the base 1. rll'he rear casing 46 is also provided with extending side portions 49 having the ends thereof butt against the ends of the side portions 4S of the front casing, 45, the said rear casing 46 being held in position by a screw connection 5() extending through the side portion 49 and threaded in the base 1.

One of the side portions 50 is provided with a suitable opening 51 to receive the bolt 27. A portion of the inlner surface 52 serves to position and guide one side of the bolt 27. A depressed portion 53 is provided on the inside of the rear casing 46 so as to reduce the bearing surface between the bolt and rear casing. One end of the stem 41 is positioned in a boss 54 dn the inner side of the rear casing 46.

If the lock is used in combination with the ordinary solid door jamb or bolt keeper and it is desired to move the bolt to a locking position, the key would first have to be inserted and the bolt 27 moved outwardly of the lock by actuating the pinion 40, after which the key would be withdrawn. If an automatically spritng actuating bolt were provided in order to withdraw the bolt 27 from its locking position, it would only be necessary to insert the key in the keyhole, at which time the bolt 27 would be automatically withdrawn and permit the door or other member to be opened.

A means is provided which will permit the bolt 27 of the lock to be actuated without the use of a key, such for example from the inside of a hall door when the lock is used thereon. As a means of permitting Such a movement of the bolt member. that portion of the web 29 of the bolt 27 havilng the series of slots 31 and 32 thereon, is made moved laterally of the bolt 27 or longitudinally of the tumbler members a distancey sufiicient to clear' the end pegs of the tumknob or handle'58 is secured to the project ing end of the stem 56 by a screw 59 or any other suitable means. The ends of the j keeper 60, 61, and the top edge 62 of the keeper and the corresponding part of the bolt in contact Itherewith are preferably tapered so as to 4accurately position the release 55 with respect to the bolt, the tumbler members, the pins and the pegs carried thereby. The accurate positioning of the release 55 is necessary in order that the pegs positioned in the tumbler membersniay pass.

freelv through the series of slots 3l and 32.

As afmeans of maintaining the release 55 in a substantially parallel position with respect to the web port-ion of the bolt, there are provided pins 63 having one end there of spaced apart and fixed in the release 55 ajnd the other end thereof extending through the web portion 30 of the bolt 27, and an opening formed inI a plate 64, which plate is also fixed to the web 30 of the bolt 27 to move therewith. i The plate 64: is positioned within the slotted opening 57 of the casing 46.

As a means of holding the release 55 in position, there are provided springs 65,

which, in the preferred form, are positioned about the pins 63, one end of the springs being in cont-act with the web 30 and the other end in'contact with the release 55. It is thus seen that'if the bolt is to be moved fromvinside the door without the use of the the kioh- 5i: grasped and pulled, which will withdraw the release 55 against a sprilng pressure out of the path of the end pegs of the`tu1'nblers and thus permit the bolt to be moved to the desired position by sliding movement of the knob 58.. Fig. 14 shows the release withdrawn against the spring pressure in thedirection of the arrows so that the said release 55 is withdrawn from the path of the pegs'19 positioned at the end of the tumbler.

l/Vith reference to the arrangemelnt of the casing it is understood thatany suitable construction may be employed for coveringtheo working parts of the lock.

It is'further to be understood that the lock may be adapted for various uses including interior and out-of-doors, safes, padlocks,

etc. In the positioning of the lock it is preferably so arrahged that the keyhole housing 9l and protective casing 47 will be embedded in Wood, metal or other material 66, as shown in Fig. 5.

If, for example, the lock is used with a solid door jamb on an outside door either with or without the spring 3.7, and it is desired to lock the door from the outside and if the person is indoors and desires togo outof-doors and then lock the door; it would first be necessary to, release the bolt 27 by withdrawing the knob 58, thus moving the release 55. outl of the path of the end peg members 19 and/moving the bolt 'to a withdrawn position when "the door may be opened. In order to lock the door in the assumed case with lthe solid door jamb, V4it would be necessary to insert the key in the keyhole from the outside and then move the bolt to a locked position by moving the bolt Vwould be withdrawn.

In order to eliminate the necessity for either withdrawing the bolt through the release from the inside and for inserting the key from the outside and turning the bolt through the pinion connection, there has been provided what `may he termed the spring slide or keeper for the lock. The said spring slide or keeper is positioned on the door jamb and eliminates the necessity of havingto withdraw the bolt from inside in order to open or close they door.

In the preferred construction shown, the x spring slide door jamb or keeper comprises a rectangular box-like casingy 67 open at one end 68 and the top 69 thereof. A. cover 70. for the casing is provided, which, in the preferred form,'has flanges 71 on either side thereof guided in grooves 72 formed in the upper edge lof the vsides of the casing 67 VIn the constructionshown, the cover is provided with a projection 73, there being provided a compression spring 74, posi- "tioned between said projection and one end 75 of the casing so that the said spring will normally tend to keep the cover 70 closed. As a means of assisting in positioning the ends of the spring 74, there are provided studs 76 positioned 'in the projection 7 3 and` 011e end of the casing 75.

At the end of the spring slide door jamb adjacent the door, there is provided' an L- shaped spring member 77 having one end thereof extending around the bottom edge of the casing and there suitably secured.

- One of the legs 78 of the L-shaped member extends inward from the end of the casing a distancesubstantially equal to the distance which the 'bolt' member 27 projects from the lock, and the other leg 79 of the L-shaped portion is of a length substantially equal .to

the width of the bolt 27, there beingkprof vided in the sides of the casing grooves 81,

. in Which the edges of the leg 79 are posir equal to the length of the projecting bolt- 27.

and the bolt is moved outwardly ci' the casing, the spring 8O will move the L-shaped member outwardly of the casing so that the upper end-of the leg 79 will be moved outwardly so as to come within the path of movement of the cover 70 and will hold the said cover in an open position against the action of the spring 74 until the door is again closed and locked. at which time the bolt 27 Will be moved inwardly of the casing and will strike the leg 78 of the spring member, thus withdrawing the outer` end of the leg 79 from its holding position with re- -spect to the top 70 and permit the spring 74 to move the top 70 to a closed position over the bolt.

" A knob or handle 82 is secured by suitable i `means to the top sliding cover 70 so that if it is desired to open the door from the inside Without the use of a key or removing the release of the lock, it is only necessary to grasp the handle 82 and withdraw the cover 70 from the casing a sufficient distance to permitthe bolt 27 to move freely out of the casing. If, kwith t-he parts in this position.

it is desired to have the door unlocked when passing outside, it is only necessary to pass out and close the door, at which time the lbolt 27'Will move within the casing and release the spring-actuated cover 70. It is thus seen that by providing a spring-actuatedsliding door jamb, it is not necessary to use a key at any time in passing from Within to the outside. The said sliding door spring door jamb is to be the subject of a .separate application.

l/It is thus seen that there is herein provided a combination lock of simple construction having relatively few parts so arranged that by the insertion only of a combination key in the keyhole of the lock, the tumbler members are directly actuated by the Ward members of the key and are moved longitudinally of the keyhole thereby, thus positioning an adjustable means carried by the tumbler mem erslso asto permit free movement-ol:l thebolt, Which may be either automatically spring .actuated in one direction or may be positively manuallyA moved' in I each direction from one side: Further, the

bolt may be provided with a release member adapted to be actuated from the side of the ,f lock opposite to that to which the key is appliedso that the said bolt may be freely moved Without the necessity of having to use a key.

Attention is here called to a very important feature of the construction, which mainly is the provision of an adjustable means coperating with each one of' the tumbler members by which the .combination of the lock may be changed, such a means including herein the provision of a plurality of interchangeable peg members for each of the tumbler members.

lf it is desired to use a lock embodying the. adjustable combination feature, certain portions of the lock shown may be omitted, such as the release member and the spring member for actuating the bolt.

lt is further to be noted that if the combination lock, having the automatic spring for actuating the bolt in one direction, is used as a hall or outside door lock in combination with the sliding spring door jamb, the pinion, stem and protective casing may be dispensed with.

1While but one preferred construction has herein been shown, it is understood that various changes and modifications may be made without departing from the spirit and scope of this invention as set forth in the claims.

The specific keeper shown and described herein is claimed broadly in my copending application Serial No. 306,784, filed J une 2G,
